java.lang.Object org.apache.axis.utils.XMLChar
This class defines the basic XML character properties. The data in this class can be used to verify that a character is a valid XML character or if the character is a space, name start, or name character.
A series of convenience methods are supplied to ease the burden
of the developer. Because inlining the checks can improve per
character performance, the tables of character properties are
public. Using the character as an index into the CHARS
array and applying the appropriate mask flag (e.g.
MASK_VALID
), yields the same results as calling the
convenience methods. There is one exception: check the comments
for the isValid
method for details.

the surrogate character range.
